These days, almost all goggles come with a double lens, which reduces fogging. If you’re shopping on a budget however, then double check, since single lenses are far less effective.

There are two fundamental types of lens to choose from: spherical and cylindrical.

Cylindrical lenses curve around the frame horizontally, but are flat from top to bottom. They are simpler to manufacture and therefore cheaper, but still offer good performance and are arguably more stylish.

A crucial factor, whatever type of lens you opt for, is ventilation. When air flows freely through the goggles it reduces their capacity to fog, so look for a pair with plenty of foam or plastic vents.

When the visibility changes, it’s important to be able to change the lens. This is easier to do with some brands than others, so keep an eye out for quick release mechanisms – like Anon‘s magnetic system show above. Some models will even come with a spare lens (usually low light) to help clinch the deal.

If you already own a helmet then it’s a good idea to check your chosen goggles are a good fit for it. The strap should easily fit around it and they should feel comfortable around the edge.

Finally, whether you wear a helmet or a beanie, silicon strips on the back of the strap will help keep your goggles secure.
